⁠RunJS MCP Server

RunJS is an MCP server that let's LLMs generate and execute JavaScript securely by running the JavaScript in a .NET sandbox using Jint.

It includes a built-in secret manager API that can use either an in-memory secret store or connect to a Postgres database.

Key features:

• JavaScript execution time, memory, and statement count can be limited by environment variables
• Scripts can use a fetch analogue that uses .NET's System.Net.HttpClient under the ood
• Scripts can also use jsonpath-plus to query resultant JSON
